Aside from access through console port, HPUX like other Unix or Linux, can be accessed through Telnet or SSH. If some how you cannot access your HPUX through these 2 methods, it may be either the service is not started or the firewall of the machine blocking your way. Solutions below are tried at HPUX 11.3.
To start the Telnet Service:
- Edit /etc/inetd.conf, search for keyword “telnet”
- If you see the line is commented (hash in front), uncomment it by removing the hash sign
- Issue command “inetd -c” to reconfigure, now the telnet service should be up.
However if you still unable to access through Telnet, try to disable the firewall by issuing this command:
In my case, after doing these 2 solutions, I able to access through either telnet or ssh.
